Understanding how people assimilate different types of information for food choices is integral to improving knowledge about diet and human health. This study evaluates the impact that 10 information signals have on the perceived healthiness of gluten. Signals include non-social signals such as personal eating experiences, scientific studies, and advice from doctors, but also includes social signals such as recommendations from attractive people, social media, the layout of a grocery store, and celebrities. An online survey of over 1,000 Americans is administered using indirect questioning where subjects are presented with a hypothetical other person and asked how the various signals would impact that person's opinion of gluten-free diets. Results show that advice from an attractive person is thought to have a slightly larger impact than reading about a new study regarding gluten, and seeing a grocery store develop a new gluten-free section has a larger impact than learning a celebrity consumes a gluten-free diet.
了解人们如何吸收不同类型的信息来做出食物选择，对于增进人们对饮食和人类健康的了解至关重要。本研究评估了 10 种信息信号对麸质感知健康度的影响。这些信号包括个人饮食体验、科学研究和医生建议等非社交信号，也包括来自有吸引力的人的推荐、社交媒体、杂货店布局和名人等社交信号。通过间接提问的方式，对超过 1000 名美国成年人进行了在线调查，让被试者面对一个假设的他人，并询问各种信号将如何影响那个人对无麸质饮食的看法。结果表明，来自有吸引力的人的建议被认为比阅读关于新的麸质研究的影响略大，而看到杂货店开辟一个新的无麸质区域比了解到一位名人食用无麸质饮食的影响更大。
